Hi all,
When I display downtimes in Icingaweb2, downtimes are listed that I cannot delete. The error message is:
Can’t send external Icinga command: 404 No objects found.

When I click on the relevant host for downtime, no downtimes are displayed for the host. I suspect that the ‘error’ lies in the query. Is there a way (perhaps with a corresponding SQL statement) to remove these ‘zombie entries’ from the downtime overview?

Kind regards

OK, I found a way to delete the downtime.
I have to open the host, find the service, click on it and then i can delete the downtime manually.
